【中文标题】iOS 8 - 无法符号化来自自定义动态框架的符号【英文标题】：iOS 8 - Unable to symbolicate symbols coming from custom dynamic framework 【发布时间】：2016-01-07 16:40:27 【问题描述】：这是我所拥有的： - ios 应用程序称为 VacationSpots（.APP 文件）
应用 dSYM 文件
名为 VSUtilities 的动态框架（.framework 文件）
动态框架 dSYM 文件
这里是示例项目源代码：https://www.dropbox.com/s/nl32xlk98lnl1mv/VacationSpots.zip?dl=0
我通过强制解开一个 nil 选项使应用程序在启动时崩溃。
以下是符号化崩溃报告的一部分。请注意，VSUtilities 调用没有符号化：

【问题讨论】：
【参考方案1】：今天遇到了类似的事情。我的情况有两个问题：
.app 中的 .framework 无法获得“足够索引”/获取 mdfind 的所有元数据，例如 kMDItemDisplayName，除非我将其移出 .app。
symbolicatecrash 使用带有“kMDItemContentType == public.unix-executable”的 mdfind，而我的框架可执行文件的真正 kMDItemContentType 是“public.data”。
通过以下方式解决它：
将 .framework 从 .app 中移出（在我的例子中，我将所有的东西都移到了桌面，以确保它被正确编入索引）
修改（复制） symbolicatecrash 以不仅查找“kMDItemContentType == public.unix-executable”，还查找“kMDItemContentType == public.data”
附：您可以使用 mdls 来获取文件的索引元数据属性：
MacBook-Pro-GE:~ eg$ mdls -name kMDItemContentType ~/Desktop/OPASAppKit.framework/OPASAppKit
kMDItemContentType = "public.data"
至于symbolicatecrash的修改版本，我不确定我是否可以按原样发布，但这里有一个差异，只有一行发生了变化。

顺便说一句，看起来 Xcode 也使用 symbolicatecrash 进行符号化，因此在 Xcode 中修补脚本让我也可以使用自定义动态框架来符号化崩溃。
【讨论】：
太棒了。谢谢你的提示。我一定会试一试的。 你好 Grigory，你能复制和粘贴你的 symbolicatecrash 文件吗？另外，您是如何确定您的框架的 kMDItemContentType 类型是“public.data”的？ 你好格里高利。非常感谢你帮助我。我向 Apple 开了一张支持票，他们给我发电子邮件说我需要为此打开一个错误报告。我也这样做了。我将更新错误报告以指向该线程。谢谢！以上是关于iOS 8 - 无法符号化来自自定义动态框架的符号的主要内容，如果未能解决你的问题，请参考以下文章
